Molecular Identification and Phylogenetic Analysis of Marine Actinomycete Isolates
ثبت نشده
چکیده
Molecular ecological studies have revealed that deep-sea sediments contained more than 1300 different actinobacterial operational taxonomic units, most of which were predicted to represent novel species, genera and families (Stach and Bull, 2005). It is not surprising, therefore, that members of 50 genera, including 12 novel genera, of actinobacteria have been isolated from marine habitats (Goodfellow and Fiedler, 2010), but less effort has been devoted to molecular characterization and phylogenetic studies of actinobacteria inhabiting marine sediments. A fundamental understanding of their phylogenetic diversity and eco physiology, is essential to assess the ecological significance of this relatively overlooked component of the marine bacterial community (Gontang et al., 2007).

Molecular identification and phylogenetic analysis of chronic bee paralysis virus in Iran
Chronic bee paralysis virus (CBPV) is an unclassified polymorphic single-stranded RNA virus. Among the viruses infecting honeybees, CBPV is known to induce significant losses in honeybee colonies. In this study, a total number of eighty-nine suspected apiaries from four regions of Iran (including Mazandaran, Khorasan Razavi, Hormozgan, and Kurdistan) were sampled and submitted for molecular ide...

Actinomycetes are inexhaustible producers of commercially valuable metabolites, are continually screened for beneficial compounds. The taxonomic and phylogenetic study of novel actinomycetes strains are mostly based on conventional methods and primary DNA structure of 16s rRNA. Although 16s rRNA sequence is well accepted in phylogeny studies, its secondary structures have not been widely used. ...

Background and Aims: Marine Actinomycetes are gram-positive bacteria that sometimes are free, saprophytic or plant and animal-associated, including marine sponges. More than 75% of antibiotics and antimicrobial compounds are produced by actinomycetes. In recent years, due to the need for new drugs, marine microorganisms have been considered as new sources of potential production of significant ...
